5 Data Science Jobs

As more organisations across sectors awaken to the far-reaching benefits of having skilled data professionals on board, the demand is projected to grow by 28% by 2026, notes Subramanyam Reddy, founder and CEO, KnowledgeHut, a global edtech firm.

Enterprises across sectors -- ranging from automobiles, defence, logistics and banking to agriculture, healthcare, food and beverage and more -- have realised the ability to leverage data generated by their users to influence a wide range of desirable outcomes, in turn, fuelling the Data Science boom.

Organisations are relying on a data-first practice to remain relevant and competitive in modern times. But a lack of data literacy can seriously slow down business growth.

With disruption becoming more than a buzzword, there’s a need for data scientists who can actually wrangle data, create models out of it, and back business decisions at a higher level.

By 2025, Asia is estimated to have 170 zettabytes (1 zettabyte is 1 trillion gigabytes) of data, of which, enterprises will contribute 60%.

Clearly, data is revolutionising the way enterprises operate.
